To ((7/1 "who/1r it may cancer/z:

Be it known that I, Hanan A. LARNARD, a bevel-gear,

of Moline, in the county of Rock Island and l State of Illinois, haveinvented certain new and useful Improvements in FlouePackers; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawi lugs,and to the letters of reference marked thereon, which form, part of thisspecification. in which- I Figure 1 is a front elevation of my improvedflour-packer. Fig. is a side elevation of the same. I3 is a sideelevation showing a modification. Fig. l is avie'wol' the gearingframedetached. Figs. 5 and 6 are details.

This invention relates to improvements in flour-packers; and its objectsare to provide improved mechanisms for starting the packer and forautomatically stopping the same, and, further, to improve the supportsof the gear iug of the packer. These objects I attain by the presentinvention, which consists in the novel construction and arrangement ofparts hereinafter d escribed, illustrated in the drawings, andparticularly specified in the claims hereto appended.

Referring to the drawings by letter, A designates the main frame of thepacker, consisting of two vertical uprights, a a, suitably connected attop and bottom, which may be provided with any suitable guides for avertically-reeiproeating platform, XV, hereinafter referred to. At thetop of frame A is mounted a rectangular frame, B, made of cast metal.This frame has bearings 19 I) cast integral on its upper and lower railsand forming half of the journal-boxes of the vertical anger or packershaft 0, which is confined in bearings 12 b by half-boxes c c, bolted toframe B, as shown.

At one end of frame B is formed an offset arch, D, provided with abearing, (1, which stands at right angles to bearings 19 b andcorresponds with a similar bearing, E, formed on the adjoining end railof frame B, as shown, the latter bearing, E, however, being lengthened,as shown, to properly align and support a short shaft, F, which isretained'in bearing E by a cap, 0, bolted to frame B, as shown. Theshaft F, it will be seen, stands at right angles to shaft 0, and bearson its inner end meshing with gear on shaft 0. On the outer end of shaftF is mounted the cup wheel of a friction-clutch, G, hereinafter referredto. Gear f and wheel 9 are set on shaft F,so that it is kept from anylongitudinal play in hearing E.

H designates a shaft, one end of which is supported and journaled inbearing (7, being retained therein by a cap, 72., as shown. Shaft H liesin line with shaft F, and bears on its inner end, within. offset D, theiuorable disk g of the friction-clutch G, as shown, which is properlymounted on shaft H, so that it can be engaged with cup-wheel g andimpart motion to shaft F. The other end of shaft H may be journaled inany suitable support in the building where the packer is mounted, andmotion is imparted to said shaft by any proper power. The shafts F and Hconstitute a sectional counter-shaft by which the packer is operated.

I indicates a movable arch. bolted to the upper rail of frame B throughopenings i-i therein, so that the arch will stand directly over theupper end of shaft 0.

J designates an oil-cup fitted on the upper end of shaft C, andj is aset journal screw mounted in arch I and entering cup J, so that theshaft C will be kept from rising in its bearings on frame B. Cup J canbe filled with oil to prevent wear of the parts J and j.

i 1" are openings in the lower rail of frame B, corresponding inposition to the openings 2' 2', so that, if desired, frame B can be reversed and shafts G and F be on the lefthand side of the machine.

K K are similar arms or studs projecting rearwardly from the arch D atequal distances from bearing d. Stud K in this instance forms thepivotal support for a lever, L, the bifurcated upper end of whichloosely engages the hub of the movable disk g of clutch G, as usual, sothat by oscillating lever L the parts 9 and g may be engaged ordisengaged. hen the frame B is reversed, lever L is mounted on stud K.The lower end of lever L is pivotally connected to one end of toggle-1ever M, the other arm of which is pivoted to a proper keeper on themain frame A, and this toggle-lever M is pivotally engaged at its jointwith a depending rod, N, by which the toggle-lever is opened orextended.

on designates a coiled spring connected with the upper end of rod N andto a point on the frame 13, and serving to retract the rod after it hasbeen depressed, and there by retract the toggle-lever. It will beobserved that when the toggle-lever is extended the lever I, is shiftedso as to throw the parts of the friction-clutch into engagement and keepthem so until the lever is released and retracted, so that by depressingor elevating rod N the packer will be set in operation or stopped. Therod N extends downward nearly to the base of the machine and is attachedto an angular dog, 0, playing vertically through a keeper, I, secured tothe main frame. \Vhen rod L is depressed, the dog 0 is engaged byitstooth with the side of keeper P, and the dog has an inwardly-projectingbent arm, 0, which is adapted to be struck by a lug, '1 011 the platform\V and knocked outward, disengaging the keeper -P and releasing rod L.The rod N is connected with a short hand-lever, Z, pivoted to theupright a above keeper P, by which the rod can be depressed whendesired, or after it has been released by the platform.

The platform WV, which is adapted to support a barrel or sack whilebeing filled, is operated by means of a chain, Q, which passes underfriction-pulleys on the top rail, 10, of the platform-support, and isattached to grooved cone-drums q g on a horizontal shaft, R, suitablyjournaled on the main frame at the rear thereof and extending outward onthe side be low shaft H, and receiving motion from a pulley, s, on thelatter shaft by a belt, S, and a pulley, r, on shaft R, as shown. Belt Sis made very slack, however, so that it has to be tightened in order tooperate shaft B. This is accomplished by means of a tightener, T,composed of a bifurcated angular frame mounted onshaft R and embracingpulley '7', and carrying in its upper end a friction-pulley, t, asshown. The lower end of frame T is pivot- .ally connected with the upperend of a stiff push-rod, U, which is operated by a treadle, u,

secured to the floor at the side of frame A, as shown, in convenientposition to be operated by foot. The pulley-t stands within belt S,

which is preferably crossed and bears against theinner face thereof, asshown.

The belt S is used solely to cause the lifting of platform IV, and itsdescent is by gravity, regulated, however, by means of a frictionwheel,V, on shaft R, surrounded byafrictionband, 1:, one end of which is fixedto the main frame, and the other end is connected to an oscillatingpivoted scale-beam lever X, which ported on frame A above platform \Vand surrounding shaft 0, which latter is provided within the cylinderwith a worm or worm-fingers, which force the material down in said tube.The upper end of cylinder Z is provided with an enlarged receiving mouthor funnel, a, into which the material is fed.

WVhile the rod N can be readily depressed by hand, as described, yet, inorder to expedite the working of the packer, I employ another means fordepressing the rod from treadlear. To do this a chain, L, is attached torod N, above the dog O,'and passed over bracketpiccc M, attached to oneupright a, so as to keep the chain from interfering with the dog andcause the chain when depressed to draw rod N inward, and thereby causethe automatic engagement of dog 0 with its keeper. The outer end ofthe'chain is attached to the treadle u, as shown.

In operation a barrel or sack to be filled is placed upon platform IV.Treadle a is depressed by the foot, simultaneously causing thetightening of belt S and the depression of rod N. Belt S causes shaft R,to rotate, winding chain'Q and lifting platform IV, with the barrel orsack, into which cylinder Z enters and delivers the material. Thedepression of rod N engages dog 0, causing the closing of parts 9 and gof clutch G, so that shaft C is rotated and begins to forcibly feed theflour through cylinder Z. As soon as platform is sufiiciently elevated,the treadle is released, stopping the rotation of shaft R and applyingthe'brake thereto. The weight on the brake-lever is so adjusted as toovercome the-gravity of the platform and require a certain downwarddegree of pressure to be expended upon the platform to lower it.pressure is imparted by the worm on shaft 0 as the material is packed,so that the barrel is filled properly. The cone-drums on which chain Qis wound are so graduated as to diminish the leverage of the chain onshaft R as the platform descends, and thereby compensate for the weightof the material in the barrel. hen the platform descends, the lug.

yis so arranged as to strike the dog 0 and cause it to disengage thekeeper, and the parts acting as already described cause thedisengagement of the parts g and g of clutch G from shaft F and thestoppage of shaft 0, and consequently of the packing operation.
